Meeting has that reliably to locate required cushioning effect and elasticity and adaptability of human body is required the back lining materials of characteristic be plastifying polrvinyl chloride (PVC) foamed materials.This a kind of material the United States Patent (USP) of applying for _ _ _ explanation is arranged in number (agent's registration number is JBP-306), this application and the present invention are same agent agencies, its full content at this as with reference to introducing.Many different classes of back lining materials all can be used in this technology, but the most suitable be that volume density is about 30 pounds/foot
3, the PVC elastic foam product by " Gaska, Tape, Inc.ofElhart, Indiana " sale of about 30 mils of thickness.For simplicity, remaining explanation please refer to this specified elastomeric material.The various materials of applying for a patent that propose equally, above also are suitable for.
Paste the technical process of bandage strip by just understanding better from the continuous reel charging of elasticity PVC foamed materials manufacturing referring to Fig. 1 to Fig. 6.At Fig. 1, elastic backing material 10 contains ready-formed elasticity PVC foamed materials, introduces through vacuum drum 15 from reel 8, and at the rotary drum place, the tensile force in the elastic backing material 10 is weakened, and this will describe in detail below again.Elastic backing material 10 passes through deflector roll 40 then.Though do not illustrate on the figure, can adhere to medical gel or other material on the centrage of back lining materials fabric here.From the non-woven pad fabric 11 process deflector rolls 41 that reel 9 is introduced, this deflector roll scalable elastic backing material 10 is with the required gap of gel between the pad fabric 11.The envelope paper of introducing respectively from reel 18 and 19 of throwing off 32 and 33 covers on the lamination sheet that contains pad fabric 11 and elastic backing material 10.The envelope paper that can throw off is preferably overlapping along the fabric center place of whole cloth pad area.Fig. 4 is that combined material is put the envelope paper viewgraph of cross-section afterwards that can throw off.
Combined material cuts off the station through one then, and the cutter 21 and 22 that cuts off wherein cuts into horizontal fillet 23 with material.Fillet under cutting is delivered to package station (not shown on the figure) by belt conveyer 24, and before sterilization, these independent fillets are packaged in the sealing bag.The cross-sectional view of the fillet 23 under cutting is shown in Fig. 5 once more.
In order to guarantee that each layer in the binder can keep together, and preferably adopts the binding agent adhesion.Bonding preferably adopts and is coated with sticking method or other method easily continuously automatically so that on the surface of elastic backing material 10, be coated with the last layer binding agent continuously, make pad fabric 11 and can seal off paper 32 and 33 adhesions thereon.Automatically being coated with sticking method continuously is known on technology, U.S. Pat-4,622 for example, 089 described be exactly directly to smear viscose glue.
In a typical manufacture process, in order to reach high yield, combined material is to be input to continuously in cutting knife 21 and 22 under a speed of setting.At Fig. 1, feed roller 25 and 26 provides essential speed and control combination material to make binder.Feed roller 25 and 26 is from reel 8,9 like this, and 18 and 19 pull out bandage material.Feed roller 25 and 26 is preferably by computer control.Because back lining materials 10 is elastic, if be merely to pull out material from reel 8 on feed roller 25 and 26, because the relation of tensile force, material just only can be simply by draw down, and the tension force on the material just can not discharge before arrival cuts platform.Therefore, if there is not vacuum drum 15, the binder of making just can not cut out accurately size or not have enough elasticity to adapt to wound area.
The speed of vacuum drum 15 is preferably by computer control, and the speed of elastic backing material 10 cans be compared to the material fast 5% to 25% that other makes binder most.More preferably make the speed fast 10% to 15% of elastic backing material.
Please see Figure 6, elastic backing material 10 contacts to the arc scope of 180 degree at 0 degree with vacuum drum.Though how much not strict in the operation of this technology contact is.Needed is that vacuum drum discharges by feed roller 25 and 26 caused tension force by reel 8.Vacuum drum is made up of the internal pressure ventilating system that an outer perforated plate centers on.The structure of this forced air-ventilating system is to allow allow air flow enter forced air-ventilating system through perforated plate on needed arc length to clamp elastic backing material 10.The air-flow of vacuum suck air has as shown by arrows again, and the size of vacuum is not strict, as long as just can determine by test several times.
As mentioned above, the control of the speed of vacuum drum is the rotary speed by it, makes the elastic backing material 10 of pulling out from reel 8 faster than the speed of other material of the formation binder the process of infeeding.Like this, elastic backing material 10 is just relaxed after through its idle running drum.This relexation just can allow elastic backing material 10 enter all the other parts of technical process with minimum tension force.
Also can utilize other method to discharge the tension force that causes by feed roller 25 and 26.Such as, can adopt other additional feed roller to replace vacuum drum 15.But, additional feed roller has trend to compress the tendency of elastomeric material, stay less shatter value, so buffering effect has also just lacked some.
